Compact Wireless Instrument System for Effortless Stage Freedom

Going wireless has never been so straightforward. The Boss WL-20L Compact Wireless Instrument System replaces your guitar cable with a lightweight transmitter-receiver set that pairs automatically in seconds. Operating in the 2.4 GHz band, this digital system gives players a 110 dB dynamic range and 20 Hz–20 kHz frequency response. Live performers and those recording directly into an interface both benefit from cable-free setups while maintaining full signal detail.

BOSS Proprietary Wireless Technology with 2.3 ms Latency

The same wireless technology BOSS debuted in the Katana-Air amplifier powers this unit. Selecting from up to 14 compatible channels, the system ensures dropout-free performance even when several musicians use wireless gear simultaneously. Unlike the WL-20, this model omits cable tone simulation to preserve the highest possible frequency detail for active pickups and line-level sources.

Wireless Performance and Battery Specifications

Core technical details let you quickly judge if this system fits your stage and instrument needs.

• Operating Frequency: 2.4 GHz — the device automatically chooses the cleanest channel from 14 available options
• Latency: 2.3 ms — so low that picking dynamics are indistinguishable from a cable
• Transmission Range: 15 m line-of-sight — roam freely on stage or between rooms at home
• Rechargeable lithium-ion batteries give 12 hours (transmitter) and 7 hours (receiver), with a full charge in 3–4 hours via micro USB

Ideal for Active-Pickup Players and Acoustic-Electric Performers

If you play active humbuckers, acoustic-electric guitars with onboard preamps, or line-level instruments like a keytar, you'll appreciate what this model delivers. This is an excellent solution for gigging musicians who want robust wireless performance without frequency coordination. Studio users enjoy the tidy, cable-free workspace when plugging the receiver into an audio interface. Up to 14 systems can run in parallel, making it suitable for bands and multi-player practice environments.

BOSS WL Series — Born from the Katana-Air Wireless Platform

BOSS developed the WL series out of the wireless platform first used in the Katana-Air amplifier. Thanks to that technology, compact digital wireless is now capable of audio quality once reserved for much pricier systems. The WL-20L brings this engineering to a pocket-sized device, providing professional-grade wireless for everyday musicians without frequency management headaches or bulky transmitters.
